What type of data is reported by amateur radio propagation reporting networks?

  1. Solar flux
  2. Electric field intensity
  3. Magnetic declination
  4. Digital-mode and CW signalsRespuesta correcta

Explicación

These networks are made up of receivers that automatically decode beacons and ordinary on-air transmissions using CW and machine-decoded protocols and publish what they heard, so what they report is signal reception. Solar flux, electric field intensity, and magnetic declination come from geophysical observatories rather than from amateur reception reports.
